The music catalogue world is celebrating one of Hollywood's truest living legends with two, count 'em, two, compilations next month.

Whether you're a die-hard film score collector or a mere appreciator of good movie music, John Williams has made a mark on your consciousness. His list of credits spans decades, first as a Juilliard-trained pianist working under the greatest batons in Tinseltown (that's him plunking the low notes in Henry Mancini's iconic Peter Gunn theme), then a light, jazzy composer and arranger of some renown (this period saw his first Oscar nod, for 1967's Valley of the Dolls). But it was his transformation in the 1970s to ultra-symphonic composer for disaster films (The Towering Inferno, The Poseidon Adventure) and mega-blockbusters (JAWS, the Star Wars, Indiana Jones, Jurassic Park and Harry Potter film series, E.T. the Extra-Terrestrial, Superman: The Movie and others) that made him a household name, the likes of which had not been seen in generations with the likes of Max Steiner, Alfred Newman and Erich Korngold.

Williams' career has seen five Oscar wins and 45 nominations (tied with Newman for the second-most nominations in history), 20 Grammys, three works on the American Film Institute's list of the 25 greatest film scores of all time (including list-topper Star Wars (1977)), a healthy tenure as the conductor of the world-famous Boston Pops Orchestra from 1980 to 1993 (Williams remains their conductor laureate and performs with them annually) and some of the most indelible themes for television ever written. (His "The Mission" is still the theme for NBC's nightly newscast, and the network will use his many pieces for their Olympic coverage; he has written pieces for the 1984, 1988, 1996 and 2002 games.) And Williams has steadfastly refused to retire, even as he approaches his 80th birthday on February 8: last month, audiences heard the soundtrack to War Horse and The Adventures of Tintin: The Secret of the Unicorn, directed by longtime collaborator Steven Spielberg, and he will pen the music for the director's forthcoming Lincoln in addition to several new chamber works and a typically robust schedule of live conducting gigs across the country.

So how does one celebrate such a rich musical legacy in just a few CDs? Sony Classical and Decca have each taken up that task this year - and you can find out more after the jump!

Sony Classical, a label with which Williams has enjoyed a long-standing relationship with for over 20 years, will release a new compilation, A Celebration!, in honor of Williams' 80th birthday. While some of his legendary works are represented, including JAWS, Star Wars and E.T., a surprising portion of the disc is devoted to recent film works (War Horse, Tintin, 2008's fourth Indiana Jones film), underappreciated scores (the 1995 remake of Sabrina, 2005's Memoirs of a Geisha) and concert works ("The Mission," "Elegy for Cello and Orchestra," recorded with Yo-Yo Ma in 2002). One vault track rounds out the set, a fitting set of variations of "Happy Birthday to You" recorded under Williams' baton in 1999.

Before Williams signed to Sony Classical, much of his work with the Boston Pops was released on the Philips label. That period is being explored in a new reissue by Decca Records, also titled A Celebration. This set is slightly more diverse, covering some classic Williams performances of both his own works and other classic moments from film scores, Broadway musicals and jazz standards over two discs. However, the set is identical to Philips' Encore! compilation from 2004 - so if you've already got that on your shelf, there's no need to pick this one up. Still, both look like excellent tributes to a man quite worthy of them.

Sony Classical's A Celebration! hits stores February 28, while Decca's A Celebration is out a week earlier. Order links and track info are below.
